Answer:
4<C
<10
Step-by-step explanation:
Theorem: Given a triangle with sides A, B and C the sum of the lengths of any two sides of a triangle must be greater than the third side:
1. A+B>C
2. B
+C
>A
3. A+C>B
Thus given two sides of A=3 and B=7 C can be:
7
−3<C
<
7+3
C range
4<C
<10
By using the given information about the inverse relation, we will get:
- Equation: y = -28/x
- Solution: y = -14
<h3>
How to get the relation between x and y?</h3>
First, we know that y varies indirectly with x, then we can write the relation as:
y = k/x.
Where k is a constant.
Then, we know that when y = 7, we have x = -4.
Replacing these we can find the value of k:
7 = k/(-4)
7*(-4) = k = -28
Then the relation between x and y is:
y = -28/x.
Now, we want to find the value of y when x = 2, then we just replace that in the above equation:
y = -28/2 = -14
So we have:
- Equation: y = -28/x
- Solution: y = -14

Answer:
8
Step-by-step explanation:
if you have 6 pounds and you use 0.75 pounds per then you can make 6/0.75 dinners = 8
The <span>height of the tower. is 27 m
Now, we write h/x = tan 45
i.e h/x = 1
i.e h = x ...........................1.
Now, h/(x+20) = tan 30
i.e </span> (x+20)/h = 1/tan 30
or (x+20) = 1.73h
or from equation 1 ,
h+ 20 = 1.73 h
20 = 1.73h - h
h = 20/0.73
or h = 27.39 = 27 m
